Objective To immunize BALB/c mice with type 3 musearinic acetylcholine receptor polypeptide (M3RP) and to evaluate the role of M3RP in SS. Methods Four-week-old BALB/e mice were immunized with M3R polypeptide 213-228 (M3RP) on days 0, 14, 35, 56, and were re-immuniged on days 65, 84, 105, and one mouse was killed every 2 to 3 weeks. The mice of the control group were immunized with submaxillary gland homogenate, GST, and PBS. The animals were analyzed for the presence of anti-SSA,anti-SSB, RF, ANA, anti-a-fodrin and anti-M3RP in sera by immunofluorescenee or ELISA. The cytokines of IFN-γ IL-2 and IL-10 were measured with ELISA. Salivary glands were examined by H&E staining and immunohistochemical analysis. Volume of water drinking by each groups were calculated. Results BALB/e mice immunized with M3RP and submaxillary gland homogenate developed an immune response directed against M3RP, α-fodrin and ANA, but no antibodies against SSA, SSB and RF were found. Furthermore, lym-phocytic infiltrates in the salivary glands of immunized animals were observed 50 days after first immunization of M3RP and submaxillary gland homogenate. The serum IFN-α in mice of M3RP, submaxillary gland ho-mogenate, GST and PBS was (62±6), (89±5), (30±5) and (19±6) pg/ml respectively, and IL-2 was (12.6±1.6), (19.8±0.4), (3.9±0.9), and (4.9±1.1) pg/ml respectively (P<0.05). No difference was found in the level of serum IL-10 among the four group. Expression of α-fodrin was found only in submaxillary gland in M3RP and submaxillary gland homogenate groups of mice, but not in PBS and GST controls when studied by immunohistochemical analysis. Conclusion These results suggest that BALB/c mice immunized with M3RP are reminiscent of human SS, and M3RP as an autoantigen participates the development of SS.

Objective To clarify the relation between the expression of Foxp3 in peripheral blood and plasma transforming growth factor betal (TGF-β1) and the activity of systemic lupus erythematosus (SLE). Methods Foxp3 mRNA expression of 28 active SLE patients, 13 inactive SLE patients and 16 healthy controls was determined by polymerase chain reaction. Active SLE patients were followed up; Foxp3 mRNA expression of 20 active patients was measured in the stable status and the plasma TGF-β1 was measured by ELISA in the active and stable status. Results The active SLE patients showed reduced levels of Foxp3 mRNA than the inactive SLE patients (P<0.01) and the healthy controls(P<0.01). Expression of Foxp3 mRNA and the plasma level of TGF-β1 in 20 SLE patients were both higher in stable status than in active status, Conclusion The expressions of Foxp3 mRNA in peripheral blood and TGF-β1 in plasma has significant inverse corelation with disease activity, which suggests that regulatory T cells may play an important role in the pathogenesis of SLE.

The systematic approaches of metabonomics are similar to the essential attribution in concept of the wholism for traditional Chinese medicine (TCM) theories. The metabonomics had been progressively utilized to study the TCM theories, such as "ZHENG" (synelromes), or the systematic mechanism of Chinese materia medica (CMM) and its formulae by animal models, and toxicology in recent years. These studies almost focused on the responeses of endogenous metabonome to biological stimuli or genetic manipulation (pharmacodynamics and toxicology) by TCM theory of "ZHENG", while less involved the precess of formulae itself and its dynamic changes (pharmacokinetics) by TCM theory of "FANG". The "treatment by differentiating syndrome" and "Correspondence of FANG-ZHANG" is the quintessence of TCM theories. Consequently, in this idea, the application of PK-PD methods based on metabonomics and "FANG-ZHENG correspondence" to investigating the compatibility of the formulae in TCM theory is discussed in this paper.
